I've had my sights set on a single shot break action rifle for a while, but with H&R/NEF and Rossi no longer making new rifles, it's difficult to find them for a good price anymore and nearly impossible to ever get a second barrel unless bought as part of a package deal. Thus, enter Thompson Center.
While the price is higher than I'd like to pay, I know that the quality of these guns is unmatched.
The quality used to be unmatched but rumor has it that it's not as good since Smith and Wesson acquired the company. I wouldn't know because all of my Encore stuff is from when the company was privately owned.
What I'd like to know is with a 15 inch barrel, what's the max range I can expect with .308? I'm looking for 500 yards max, but 400 is acceptable.
Some have shot them at the 400 to 500 yard range but with any handgun velocity is not going to be equal to a rifle and thus the trajectory at extended ranges will be a lot steeper. I would say 200 yards is easily doable with 250 to 300 yards more challenging. Four hundred to 500 yards would be very challenging to a lot of rifle shooters.
What kind of MOA can I expect?
I have 3 different barrels capable of about 1.5 inches at 200 yards; the cartridges are 375 H&H Magnum, 444 Marlin and 460 Smith and Wesson Magnum. I would say with a good barrel, the 308 Winchester could do just as good and maybe even better.
Also, how much would it be for a .223 barrel?
If you're wondering about range and precision, about the same as a 308 Winchester.
Final question: How is long range shooting of a pistol chambered in a rifle cartridge different from rifle shooting? Is it a challenge to adapt to?
Yes, it's quite challenging.
For best results, I'd go with a barrel from Match Grade Machine, a Leupold handgun scope in the 2.5 to 8X range, the SSK Industries T'SOB scope mount with 4 rings and a pistol Encore frame on which a Bellm spring kit had been installed to make a lighter and better trigger.
Note, handgun frames are the same as rifle frames but you cannot legally use frame that was initially sold/assembled as a rifle to assemble a handgun. It is legal to assemble a rifle out of a frame initially assembled as a handgun and it would be legal to turn such a frame back in to a handgun.
Regarding the Bellm spring kit; you can do the trigger job with said kit all by yourself if you're handy with tools and reading directions; if not, there are gunsmiths who'll do the trigger job with the kit. Also don't buy into all the other hype on the Bellm web site about shims for headspace, Bergara barrels, etc.
